SET-STILL TENSION FOR \VOOF-WIBES. 7'

Specification of Letters Patent.

Patented Feb. 2, 1.909.

Application filed. July 9, 1908. Serial No. 442,676.

To all whom it may concern:

Be it known that 1, ORANGE S. STURTE- VANT, a citizen of the United States, and a resident of Adrian, in the county of Lenawee and State of Michigan, have invented a certain new and useful Set-Still Tension for Woofires; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to wire handling apparatus, and has particular reference to means for use in connection with wire fence.

looms for facilitating an unwinding of the woof wire from itsbundle without tangling as it is intermittently fed to the loom during the weaving operation.

Considerable difiiculty has been experienced in wire fence weaving due to the tendency of wire in the Woof-wire bundle to become tangled due to the sudden jerking of the wire at each time a sectionof the same is fed to the loom, thus making it impossible to take thewire out of the bundle and necesthe wire. I

The object of my invention is the provision of a simple and eliicient means which will prevent a tangling of the woof-wire when being unwound from its bundle and will not allow the wire to lead off the holder or setstill spool faster than the loom will weave the fence, thus obviating the objections incident to the use of the devices heretofore employed for such purpose. V

The operation, construction and arrangesitating a stopping of the loom to untangle ment of the parts of the invention are fully described in the following specification,

which the woof-wire of the fence beingwoven is intermittently paidout to theloom as the weaving operation requires. This ing both the dropping of a wire bundle thereover and the uncoiling of the wire from its bundle as it is fed to the loom. An annulus or ring 3 is preferably secured to or fitted snugly over the upper end of the set-still spool to form a peripheral flange therearound for holding the wire in position on the spool in operation, and is adapted to be removed therefrom when it is desired to place a bundle 2 on the spool or remove one therefrom.

Secured to the top of the spool 1 centrally thereof, as by screws passing through apertures l therein, is a friction-disk or plate 4, which has a studs rising therefrom in axial relation to the spool, as shown. As arm 5 has one end loosely mounted on the stud 4 and is frictionally held to the plate 4 by the cooperation therewith of the upper friction plate 6, which is also mounted on the stud 4P and held in frictional engagement with the lower end by the threading of a nut 7 to the end of the stud, thus tending to tension the arm 5 so as to retard its revolving movements.

The outer end of the tension-arm 5 preferably extends slightly beyond the outer edge of the ring or annulus 3, and is provided at such end with an eye 8 through which the wire 2 passes as it unwinds from its bundle.

In order to facilitate a removal of the ring 3 and the placing of a wire bundle on the spool, the arm 5 is made in two sections, which are pivoted together, as at 9, for horizontal folding movements. A latch 10 is pivoted to the inner arm. section and is adapted to engage the outer section to maintain itin rigid longitudinal relation to its companion except when the latch is thrown to open position.

It is apparent that if the arm 5 were permitted to turn freely on the set-still spool, or if no tension means was brought to bear on the wire strand in its unwinding action, the jerking of the wire due to the intermittent and sudden acting of the feeding mechanism thereon would cause it to unwind from its bundle more rapidly than required by the weaving operation and thereby soon cause it to become tangled in such a state as to render it impossible to draw the Wire from the bundle. By tensioning the arm 5 as described, or in any other suitable manner, the unwinding of'the wire from th spool is sufliciently retarded to prevent the wire leading oil the spool faster than the 100111 will Weave the fence, thus making it impossible for the Wire to become tangled.

I Wish it to be understood that I do not desire to be limited to the exact details of construction and arrangement of the parts shown and described, as obvious modifications will occur to persons skilled in the art.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is.

1. In a device of the cla. combination of a spool, a revoluble guide arm mounted on the upper end of the spool, said arm comprising plurality of sections capable 0]: relative movements to shorten the length 01": the arm, and means "for frictionally resisting a tree turning of such arm.

2. In a device of the class described, a I

described, the

frusto-conical spool having its small. end up,

cooperate to prevent a tree turning of the arm.

3. In a device of the class described. a Wire bundle holding spool, a. removable peripheral flange at its upper end and a revoluble coaxial Wire guiding arm carried at the upper end of the spool and tensioned against tree revolving movements said arm comprising a plurality of sections capable of relative movements to shorten the length of the arm.
